Description

Improved crusher for pruning remains.

Object of the invention

The present invention relates to a Improved crusher for pruning remains, whose obvious purpose is that of crushing and chopping the remains that occur in agricultural pruning and all kinds of loose branches.

The object of the invention is to improve the effectiveness of the pruning crushers and also obtain better results and ultimately get faster and Optimum work performance.

The invention falls within the scope of the manufacture of agricultural machinery, being of special application in the crushing of olive, fruit, vineyard, etc. branches, Extending its use in all types of crops and applications in which its use and functionality are feasible.

Background of the invention

As is known, conventional crushers they are usually machines dragged by a tractor vehicle, being generally constituted by a docking main structure precisely to the agricultural tractor, being able to have one or more feeder rollers that lift the material from the ground and what they move to a cavity in which a carrier rotor of a series of hammers or blades, while the crushing of pruning remains and similar products.

One of the problems presented by conventional crushers is that the hammers or blades are mobile or rotating, which leads to the appearance of vibrations and instability in the joint.
to.

Another drawback is that the speeds of Conventional crushers work are usually slow, so That the efficiency is very low.

Another drawback is that they occur with frequency jams in the rotor location cavity knife holder or hammers, with the consequent stops of the machine.

Also, there is the disadvantage that the Crushing is done with a granulometry of the processed material large, which reduces the productivity of the process.

Finally say that another drawback is that The main location cavity of the rotor is closed and includes a sieve to reduce crushing size, which tends to cause jams in the rotor and further slow down the work.

Description of the invention

The crusher that has been recommended has been designed to solve the problem described above, based on a series of innovations and improvements that result advantages that will be exposed throughout the present description.

More specifically, the crusher of the invention, constituting from a main structure metallic and hollow, where the blade bearing rotor is located, presents as a first feature of novelty the fact that that Cavity is open and lacks sieve.

Another novelty is that the cutting blades go mounted on fixed supports, with replaceable character, so that when the supports are fixed and therefore the blades, avoid vibrations and instabilities of the whole machine.

The cutting blades, may have different shapes, as well as the supports, have a cutting edge with a certain angle for incidence of the material, and whose angle is variable depending on the type of application of the machine.

Another feature of novelty is that cutting blades are mounted along the rotor, forming circumferential alignments, covering the entire length of the rotor, but with a lag of relative rotation to achieve a global arrangement in the form of a cylindrical fixed pitch propeller, with tendency to concur from the extremes to the intermediate zone of each of the two halves in which the total length is considered of the rotor, which aims to drag the material to two areas that correspond to the middle part of each half longitudinally, preventing it from going to the sides and preventing both the jamming or winding of the material between the rotor and the machine structure

According to the characteristics mentioned, in the rotor forms what can be considered as two propellers symmetric, which concur in the intermediate or transverse plane of each half of the rotor, acting as a double auger, so the material after the entrance to the rotor cavity forks in said cavity so that at the exit the material is better spread crushed on the ground, while avoiding accumulation and excessive wear in the middle and inside of the machine.

Another feature is that inside the structure or cavity in which the rotor is located, are established several lines of replaceable counter knives, which they go inside the diameter of the rotor cut, just in correspondence with the free zones left by the blades of cutting each other, thereby increasing the cutting efficiency and crushed by the blades. The commented portachillas They are replaceable.

A last novelty feature of the referred crusher, is that the general structure of it It has anchors to the corresponding tractor vehicle, both in its anterior part as in its posterior part, turning the crusher in reversible.

Description of the drawings

To complement the description that then it will be done and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, is accompanied as an integral part of that description, a set of drawings in where illustrative and not limiting, it has been represented the next:

Figure 1.- Shows a representation according to a frontal and partial perspective of the crusher object of the invention

Figure 2.- Shows a side view of the rotor equipped with the corresponding cutting blades.

Figure 3.- Shows a perspective view corresponding to the detail of the assembly of the cutting blades on the corresponding rotor.

Figure 4.- Shows a side view of the crusher of the invention, showing mainly the two anchors to the tractor vehicle, one in the front and one in the back.

Preferred Embodiment of the Invention

As you can see in the referred figures, the crusher of the invention is constituted from a structure main (1) with rolling means (2), and with a pair of anchors (3), one anterior and one posterior, to the corresponding tractor vehicle, turning the crusher into a machine reversible.

The main structure (1) defines a cavity open in which a rotor (4) is arranged, consisting of a cylindrical and hollow body, on which a plurality of supports (5), to each of which are fixed the corresponding cutting blades, so that in all cases on each support (5) two cutting blades are mounted (6), with the particularity that these cutting blades (6) are replaceable when fixed on the respective supports (5) by screwing or any other appropriate system.

The cutting blade edge (6) presents certain angle of incidence for the material, which is variable, with the special feature that on the rotor (4) they go arranged the cutting blades (6) forming lines circumferential, with a "α" offset of relative rotation, as depicted in figure 2, in order to achieve a global arrangement in a cylindrical and fixed pitch trend to attend, from the ends, on the intermediate zone of each one of the two halves of the rotor length (4), which leads I get the drag of the material to be crushed always towards the intermediate zones of each one of the halves, avoiding that it goes to the sides, which will prevent jams or curl of material between the rotor (4) and the internal surface of the cavity which forms the main structure (1).

Inside the cavity or structure Main (1) of the crusher, several lines of replaceable counter knives (7) that enter within the diameter of cut of the rotor itself (4), just by the areas that leave free those cutting blades with each other, causing the material to brake when hitting said replaceable counter knives, by way of stop, leaving less space for the passage of the material itself and increasing therefore the efficiency of cutting and crushing by part of the cutting blades (6).

The material is dragged into the cavity that defines the main structure (1), to be crushed by the cutting blades (6), using feeders (8) arranged parallel to the rotor (4), turning those in directions contrary to the introduction or drag of material towards the interior where the commented rotor (4) is located.
